ROUNDHOUSE.

SPECIFICATION forming part of Letters Patent No. 677,929, dated July 9, 1901.

Application filed April 30, 1901. Serial No. 58,125- (No model.)

To all wha /1t it may concern.-

Be it known that LEUGENE F. BRADY, a citizen of the United States of America, residing in the city of Altoona, in the county of Blair, in the State of Pennsylvania, have invented a certain new and useful Improvement in Roundhouses, of which the following is a true and exact description, reference being had to the accompanying drawings, which form a part thereof.

My invention relates to the construction of 1ocomotive-roundhouses, and has for its object, primarily, to provide for an improved construction and combination of the roundhouse with trolley-supported doors for opening and closing the passages by which the engines enter and leave the roundhouse.

A further object of my invention is to provide a convenient construction for increasing the size of roundhouses which are too small to receive the modern long locomotive.

The nature of my improvements will be best understood as described-in connection with the drawings in which they are illustrated, and in which Figure 1 is a front elevation showing my system of suspended doors. Fig. 2 is a crosssectional view taken as on the section-line 2 2 of Fig. 1. Fig. 3 is a plan view of the roundhouse on a smaller scale; Fig. 4, an enlarged view similar to that shown in Fig. 2, showing in detail the track and trolley arrangement; and Fig. 5 is a plan View show.- ing a section of the trolley-tracks with trolleys in place thereon.

A indicates the roundhouse, of ordinary construction; B, B B B, and B tracks radially arranged in the roundhouse B and B sections of track terminating in a turn-table pit, and B and B the turn-table Working in said pit, adapted to register with each of the roundhouse-tracks.

C O, &c., are the. columns forming the front wall of the roundhouse proper.

O and O are beams'secured to the columns and forming an outwardly extending bracket, as shown, the upper member 0' of the bracket supporting an extension-roof, (indicated at O and 0 indicating a downwardly extending plate secured on the outer ends of the brackets, as best shown in Fig. 4:.

D is a downwardly-extending plate also secured to the outer ends of the brackets, one such plate extending over each two successive pairs of tracks, and each said plate supporting at its lower end the two parallel trolleytracks, (indicated at D and D said tracks also extending over each successive pair of railway-tracks.

E (see Figs. 1 and 2) is a guideway situated immediately below'the trolley-tracks and between the pair of railway-tracks over which the trolley-tracks extend.

F and F are doors, the lower ends of which are held together and in proper place by engagement with the guideway E and which are supported from above on trolleys running. on the tracks D and D As shown, each door is provided with a hanger, as indicated at F", the upperends of the hangers being turned over and downward, as indicated at F so as to form supports for the pivot-pins F upon which the trolleys F are journaled, said trolleys resting in turn upon the tracks D and D F and f indicatethe handles by which the doors F and F are moved.

It will be obvious that by the construction above described the doors F and F can be made to extend over and close the doorways through which the pair of tracks B and B, for instance, extend; also, that by sliding the outer door F in front of the doorF the track B is opened, while by moving the door F behindthe door F the track B is opened. It is also obvious that my door system may be combined with any construction of roundhouse; butIhave found it especially convenient in cases where the tracks within the roundhouse are too short for modern locomotives and in which a front extension to the houses is desirable, such extension being provided for by the brackets O 0 supporting the extension-roof and also supporting the trolley-tracks for the sliding doors.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is- I 1. A locomotive-roundhouse"having radially-arranged tracks, and doorways through which successive pairs of such tracks extend, in combination with double overhead-trolley tracks D D extending over each such doorway and pair of tracks and a pair of suspended doors F and F having trolleys resting on said tracks, one each adapted to close one half the doorway so that the doorway may be entirely closed or either half thereof opened by shifting the doors on the tracks.

2. A locomotive-r0undhouse having radially-arranged tracks, and doorways through which successive pairs of such tracks extend, in combination with double overhead-trolley tracks I) D extending over each such doorway and pair of tracks, a pair of suspended doors F and F having trolleys resting on said tracks one each adapted to close one half the doorway so that the doorway may be entirely closed or either half thereof opened by shifting the doors on the tracks, and a stationary guidewayE secured between the tracks at the bottom of the doorway for holding the bottoms of the doors together and in place.

3. A loco'inotive-roundhouse having radially-arranged tracks and a series of,colun1ns O forming the front Wall of the roundhonse proper and between which the tracks issue, in combination with brackets C C extending out from the columns (J, and supporting an extension-roof C overhead-trolley tracks D D supported on the brackets and arranged in pairs to extend over successive pairs of railway-tracks and suspended doors F F supported on trolleys from the tracks D D and adapted to extend over either or both of the pair of railway-tracks lying beneath each pair of trolley-tracks.
